But Murray remains more than 1,000 points behind number two Roger Federer while the Scot needs to make up nearly 4,500 points on
his Melbourne conqueror Novak Djokovic
if he is to achieve his aim of topping the rankings.

On Tuesday Watson continued her good form, progressing to the second round of the Pattaya Open in Thailand.

Watson, who is seeded eighth for the event, was leading the world number 79, Timea Babos, 6-1 3-0 when the Hungarian teenager retired hurt.

Watson, 20, will now meet Latvia's Anastasija Sevastova, who is ranked 143 places below her, in the next round.

At the Australian Open, Watson beat Alexandra Cadantu and Ksenia Pervak before losing to fourth seed Agnieszka Radwanska, while 19-year-old Robson defeated Melanie Oudin and then upset former Wimbledon champion Petra Kvitova but lost to eventual semi-finalist Sloane Stephens.

Jo Durie and Sara Gomer were the last two British women to have been ranked in the top 50 at the same time, in 1987.

Watson broke into the top 50 for the first time in 2012 - and Robson achieved that feat in January. Britain's other women suffered contrasting fortunes in the latest rankings list.

Anne Keothavong slips two places to 144 while Johanna Konta moves up six place to 147. Elena Baltacha moves down nine places to 190.
